Description product group
  • Electrochemical combination electrode: pH and reference electrode integrated
  • The large dirt-repellent Teflon® diaphragm prevents the reference system from becoming blocked up
  • Long service life when solids are present
  • High-viscosity electrolyte combined with a salt reservoir prevents the electrolyte from 'bleeding'
  • Long service life without drifts when there is clear water with low conductivity
  • Twist protection for the sensor cable connected. This means that the cables can remain connected during installation and dismantling of the sensor, avoiding troublesome moisture on the connector contacts
  • Lead-free glass for advanced and environmentally-friendly production, use and disposal (RoHS-compliant)
